Multi Switch ATS

Multi Switch ATS (1:1 16A)

Transfer Systems

The Riello UPS Multi Switch ATS is a high availability intelligent switch that provides redundant power to connected equipment with two AC input sources. The Riello UPS Multi Switch ATS supplies power to the connected loads from a primary mains source. If that primary source becomes unavailable, the Riello UPS Multi Switch automatically transfers loads to the secondary source. The transfer time from one source according the ITI (CBEMA) chart does not impact the operation of the connected equipment as the switching occurs safely between the two input sources regardless of any phase differences. The Riello UPS Multi Switch ATS monitors the current and provides warnings when power consumption draws near the maximum rating which helps prevent downtime to the equipment.

Riello UPS Multi Switch ATS has 8 IEC 10 A and 1 IEC 16 A outlets allowing several devices to be plugged directly into the ATS without the need for an additional PDU. The units have a connectivity slot which allows for LAN connection and remote management through PowerShield3 software, Web interface, SNMP, or SSH which makes the Riello UPS Multi Switch ATS an ideal device for the IT manager who needs flexibility and protection or their IT equipment.

Multi Switch ATS provides installations with power supply continuity. Its operating principle ensures higher reliability than a single UPS, (with or without its own internal bypass).
